Telset.id, Jakarta – Because of what was born the universe? We often come across this question even though human beings have been living on Earth for many years.
The universe is formed through a process. Physicists say humans live in an expanding universe. The universe gets bigger every day.
In the past, the universe was much smaller than it is today. Our universe was once an infinitesimal and dense point or singularity.

Physicists think the dot expanded in the Big Bang. Since all evidence is broken, it’s hard to know for sure what happened when the early universe formed.
For most of history, the universe has been adorned with celestial bodies similar to those that exist today. Their location is just next to each other.
For example, when the universe was less than 380,000 years old, it was about a million times smaller in volume than it is today, and had an average temperature of 10,000 Kelvin.
It is so hot and dense that it becomes a plasma, a state of matter in which atoms are broken down into protons, neutrons and electrons.
However, physicists find plasma in many other situations in space and on Earth. Physicists have a good understanding of how this works.
But the further back you go, the more complex it becomes. When the universe was only a dozen minutes old, the soup of protons, neutrons and electrons was pretty intense.
In retrospect, things have gotten pretty sketchy. By understanding the universe when it is less than a second old, we have no theoretical physics.
It means, The phone quote from Live science, Sunday (11/27/2022), all physical theories collapsed. It is not understood how particles, forces and fields operate.
Physicists can map the growth of the cosmos using Albert Einstein’s theory of general relativity, which relates the contents of the cosmos to its history of expansion.
However, Einstein’s theory contains a fatal error. If you follow general relativity to its final conclusion, the entire universe is crammed into one solid point.
This is known as the Big Bang singularity. Singularities are often framed as the “beginning” of the universe. But remember, this is by no means the beginning.
Mathematically, the Big Bang singularity doesn’t tell us that the universe started there. General relativity has broken down and lost its predictive power.
Physicists have long known that general relativity is incomplete, it doesn’t explain gravity on the large or small scale known as quantum gravity.
To understand the earliest moments of the universe, we need new physics. There is a theory rope and quantum gravity loopbut not fully developed yet.
However, if one of these theories is correct, we might learn some interesting things about the early universe. In the case of quantum gravity loopFor instance.
The singularity is replaced by a finite chunk of space-time. However, for the theory ropeour universe originates from what is called a “landscape”.

Only further advances in theoretical physics will help resolve the confusion of ideas. So, in theory, why did the universe exist? [SN/HBS]
